Which of the following is placed in upper most highest level of ecological pyramid?
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.

Why is there less energy at the top of the pyramid?
Most of the food energy that enters a trophic level is “lost” as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy. Encyclopædia Britannica, Inc.
What is a top level consumer?
The organisms that consume the primary producers are herbivores: the primary consumers. … Tertiary consumers are carnivores that eat other carnivores. Higher-level consumers feed on the next lower tropic levels, and so on, up to the organisms at the top of the food chain: the apex consumers.

Which of the following is a top level consumer?
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. … Level 4: Carnivores that eat other carnivores are called tertiary consumers. Apex predators by definition have no predators and are at the top of their food web.
